Hello, my name is hydrogen. I am single and orphaned, I have no family. I am the most common element, I am found in stars and planets. I AM NUMBER 1!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hola my name is NICKEL!!!! I am very affluent and make up all coins, not to mention I am in foil, wire, batteries, and spark plugs. Sometimes I get green with envy, so people use me to dye glass. When I don't feel like getting too close to other elements so I produce a magnetic field to keep them away.

Hi, my name is Copper and I'm found in police mens buttons, Lady Liberty, and pennies. Some people use me to make jewelry, instruments, and pipes. I like to sail because people use me to paint ships. I'm redish brown and turn greenish with oxgen.

solubility of and unknown substance.
Purpose: Does the solubiliy of a substance change with temperature?
IV: Temperature of water (C)

10g of solid (control)	8g of solid	6g of solid	4g of solid
6 trials	6 trials	6 trials	6 trials

DV: Amount of solute dissolved (g/mL)

CuSO4 Lab
Purpose: How does dissolving copper sulfate affect the temerature of the solution?
IV: How much copper sulfate is dissolved (g)
Levels:

0g	1g	2g	3g	4g	5g
(control) 6 trials	6 trials	6 trials	6 trials	6 trials	6 trials

DV: Temperature (C)
Constants: amount of solvent (50 mL), starting temperature, temperature sensor, balance, solvent, styrofoam cup
Procedure:

Measure five 1g portions of copper sulfate on weighing papers.
Measure 50 mL of water.
Pour water into styrofoam cup.
Set up computer on books and attach temperature sensor.
Start a data run and record temperature of the water for one minute.
At 60 second intervals add 1g of copper sulfate and stir.

Lindsey: I hope to see what chemicals mix and what chemicals don't mix. I don't want to spill any chemicals or make anything explode. I think we will learn a lot soon!
The first Chemical lab was fun, hopefully we will do more fun labs soon!
Chapter 4 definitions:
Soluble: The ability to dissolve in another substance. The copper sulfate was soluble in water.
Insoluble: not being alble to dissolve. zinc Oxide was insoluble in water.
Solvent: substance in which the solute is dissolved.
Solute: Is the substance that is dissolved.
Solution: Is a mixture that appears to be a single substance but is composed of particles of two or more substances that are distributed evenly amongst each other.
Dissolve: Is the process in which particles of substance seperate and spread evenly throughout a mixture.
WE DID A QUIZ WHITH A JOLLY RANCHER!
As the solute dissolved in a solvent they mix to form a soultion.
Did you know that dissolving a jolly rancher is science?

Notes on Chapter 9

energy is the ability to do work
work is the action that results when a force causes an object to move in the direction of the force
kinetic energy is the energy of motion, it depends on speed and mass
potential energy is the energy of position or shape, depends on height and weight, stored
mechanical energy is the total of potential and kinetic energy
types are thermal energy, chemical energy, electrical energy, sound energy, light energy, gravitational potentional energy, and nuclear energy
Fossil Fuels are energy resources that formed from the buried remains of plants and animals that lived millions of years ago.
Carbon is in everything living, it is organic.
Coal, natural gas, biomass,carbon dioxide gas, and Hydronoxide Fuels are all fossil fuels.
Burning fossil fuels creates carbon emission which causes the greenhouse effect.
Renewable resources can be reused.
Non renewable resources can't be reused.
